Abstract
The emulsifier contains cationic surfactant (30-60%) and solvent and said solvent is alcohol solution. Said cationic surfactant is diquaternary ammonium salt. The emulsifier features high emulsifying efficiency, stability and adhesion.
Description
The present invention relates to a kind of cationic emulsifier, particularly a kind of double quaternary ammonium salt cation asphalt emulsifier.
In the prior art, cats product has been widely used on the asphalt emulsifier, and the emulsified bitumen of being produced is used on road pavement, the waterproofing work, the cation surface activating that emulsifying agent is used mainly is a mono-quaternaries, kind is few, costs an arm and a leg, and only is with a positive charge in the molecular structure of mono-quaternaries, the electrostatic double layer ξDian Wei that particulate forms in the emulsified bitumen is lower, shelf stable for periods is shorter, poor adhesion, the large usage quantity of emulsifying agent, the cost height has influenced the quality and the application of emulsified bitumen.Chinese patent 90107891,3 provides a kind of " the compound cation asphalt emulgent that contains wooden amine ", based on wooden amine, mixes the complex cation tensio-active agent and forms, can reduce production costs greatly, but large-scale popularization not as yet, shelf stable for periods is shorter.
The double quaternary ammonium salt cation asphalt emulsifier that the purpose of this invention is to provide a kind of stability and high efficiency has two positive charges in its molecular structure, improve the stability and the adhesivity of emulsified bitumen effectively.
Purpose of the present invention can realize by following measure: comprise bi-quaternary ammonium salt component (A) and solvent composition (B) in this emulsifying agent.Component A is the following bi-quaternary ammonium salt of general formula:
R is C in the formula
16～C
18
B component is a solvent composition, and component A is dissolved in B component, and B component is moisture 35%～50% ethanolic soln.
The composition of emulsifying agent is that component (A) is 30-60% with component (A) and component (B) total weight percent, and preferred version is 40～50%.
The production technique of this emulsifier component (A) is earlier synthetic mono-quaternaries, generates bi-quaternary ammonium salt with the reaction of single cropping ammonium then, and synthetic process is well-known, is dissolved in ethanolic soln with bi-quaternary ammonium salt and more is mixed with product.
The cation asphalt emulgent that the present invention proposes, have two positive lotuses in the molecular structure of bi-quaternary ammonium salt, make the granuloplastic electrostatic double layer ξDian Wei height of emulsified bitumen, the emulsified particle state is more stable, be not easy breakdown of emulsion group wadding, and the adhesivity to formation level is good, and under the equal situation of emulsifying effectiveness, this emulsifying agent consumption is less, preservation is longer stationary phase, cost is lower, and constant product quality is a kind of asphalt emulsifier efficiently.
The following stated embodiment describes the present invention in detail.
Embodiment 1:
The following bi-quaternary ammonium salt of 100 gram general formulas is stirred in the ethanolic soln that adds 120 grams 40%, gained 220 gram cation asphalt emulgents, product in 1000 gram pitches after adding 8.8 gram emulsifying agent (i.e. 0.4% the bi-quaternary ammonium salt) emulsifications, adhesivity is good, and can reach half a year stable storage period.
Embodiment two: 400 kilogram 38% ethanolic soln is put into mixing tank, 600 kilograms of following bi-quaternary ammonium salts of general formula are stirred adding, be dissolved into 1 ton of cation asphalt emulgent product, when producing emulsified bitumen, add this emulsifying agent (the bi-quaternary ammonium salt add-on is 0.4%) by 0.67%.
Claims (2)
1, a kind of double quaternary ammonium salt cation asphalt emulsifier comprises cats product component (A) and solvent composition (B), it is characterized in that:
Component A is the following bi-quaternary ammonium salt of a kind of general formula,
R is C in the formula
16～C
18:
Component (B) is for being moisture 35～50% ethanolic soln.
Component (A) accounts for component (A) and component (B) total weight percent 30～60%.
2, asphalt emulsifier according to claim 1 is characterized in that component (A) accounts for component (B) and component (A) total weight percent 40～60%.
